...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorm potential appears low on Friday.

...Synopsis...

An upper trough just offshore from the Pacific Coast will move
inland on Friday. Meanwhile, the NHC has Tropical Storm Priscilla
weakening as it approaches Baja by early Saturday. Moisture
associated with Priscilla will stream northward across portions of
the Southwest and Great Basin. As the Pacific trough moves eastward
coincident with increasing moisture, isolated thunderstorms will be
possible from the Southwest into the Pacific Northwest/northern
Rockies. While enhanced mid/upper southwesterly flow will be in
place, weak instability will limit severe potential.

Further east, a shortwave upper trough over the Upper Midwest will
develop southeast across Great Lakes and Lower Ohio Valley. A
surface cold front will develop southeast across the Upper/Mid-MS
Valley in tandem with the shortwave trough. Modest boundary-layer
moisture ahead of the front will support weak destabilization
sufficient for isolated thunderstorms.

Additional isolated thunderstorms will be possible across the FL
Peninsula and northward near/just offshore the coastal Carolinas
within a moist and weakly unstable airmass. Poor lapse rates will
limit instability and severe storms are not expected.
